Abstract
The invention discloses a gas well automatic liquid drainage plunger. The gas well automatic liquid drainage plunger is designed for solving the problem that a traditional plunger is low in production efficiency. The gas well automatic liquid drainage plunger comprises a fishing neck which is connected with an air cylinder sleeve, pistons of a fluid flow passage and a seal assembly, a connecting rod which is used for connection between a middle branch sleeve and a lower branch sleeve, a spring, a rubber sleeve and the like. The gas well automatic liquid drainage plunger can be refloated, can achieve complete sealing of a whole wellhole by relying on the rubber sleeve, is in no need of addition of a well opening control device, can continuously produce, uses own energy of a gas well to carry out reciprocating motions in an oil tube, achieves lifting liquid in a periodicity mode, and is high in production efficiency.
Description
Technical field
The present invention relates to a kind of gas well automatic liquid-discharging plunger, belong to oil gas field production gas technology field.
Background technique
Exploitation gradually along with the gas field, the part gas well has entered stage middle and later periods of low pressure, low yield, the shaft bottom energy shortage is carried into ground with the water with the gas-bearing formation output, hydrops appears in pit shaft, the pit shaft hydrops will increase the back pressure to the stratum, and limit its throughput, finally gas-bearing formation can be killed fully so that closing well causes huge economic loss.Water pumping gas production is the effective ways that solve " gas well hydrops ", is also to excavate to produce aqueous vapor well productive potentialities, improves one of important measures of recovery rate.Plunger lift is a kind of water pumping gas production measure, is also the jat special shape, and plunger separates with lifting gas with by lifting liquid as a kind of seal interface of solid, reduces the channelling of gas and the falling of liquid, improves the efficient of lifting gas.
The tradition plunger lift needs certain closed-in time, so that plunger falls back to the shaft bottom, thereby the pressure in shaft bottom is recovered.But the long closed-in time, not only can affect the output of gas well, but also the liquid that can order about in well pours into the stratum, and then reduce the manufacturing efficiency of gas well.
Summary of the invention
The object of the present invention is to provide a kind of gas well automatic liquid-discharging plunger, it can address the above problem well.
Concrete technology contents of the present invention is as follows:
The fishing neck outside thread that is provided with the locking inside groove connects cylinder liner, is provided with piston in cylinder liner, and piston face is provided with radially convex shoulder, upper spring locking and lower spring locking, and piston is provided with axial fluid passage, and passage top is provided with sealing seat, and the bottom is provided with hollow steel ball.Cylinder liner lower end internal thread is connected with the middle spider of locking inside groove and axial fluid passage, and middle spider lower end outside thread connects packing element, and packing element lower end internal thread is connected with the lower spider of axial fluid passage.Linking springs between middle spider and lower spider, small end is threadedly connected to the piston central bore, and the lower end passes middle spider central through bore and spring thread is connected in lower spider central bore.
The invention has the advantages that this plunger can salvage, can rely on packing element to realize that whole pit shaft seals fully, do not need to increase control head, can produce continuously, utilize the to-and-fro motion in oil pipe of gas well self-energy, property performance period act liquid, manufacturing efficiency is high.

Embodiment
Embodiment:
Further illustrate referring to figs. 1 through 3 pairs of embodiments of the invention:
Fishing neck 1 lower external thread that is provided with the locking inside groove connects cylinder liner 2, be provided with piston 3 in cylinder liner 2, piston 3 surfaces are provided with radially convex shoulder, upper spring locking 9 and lower spring locking 13, and piston 3 is provided with axial fluid passage 12, passage top is provided with sealing seat 10, and the bottom is provided with hollow steel ball 11.Cylinder liner 2 lower end internal threads are connected with the middle spider 4 of locking inside groove and axial fluid passage, and middle spider 4 lower end outside threads connect packing element 5, and packing element 5 lower end internal threads are connected with the lower spider 6 of axial fluid passage.Linking springs 7 between middle spider 4 and lower spider 6, connecting rod 8 upper ends are threadedly connected to piston 3 central bore, and the lower end passes middle spider 4 central through bores and spring 7 is threadedly connected to lower spider 6 central bore.
Working procedure of the present invention is as follows:
1. plunger is up
When plunger arrives the down-hole and is located the device top, gas and liquid enter packing element 5 by the fluid passage of lower spider 6, pass through again the fluid passage of middle spider 4 and piston 3, enter cylinder liner 2, along with the increase of gas, under the effect of gas and liquid, hollow steel ball 11 is set on sealing seat 10 by jack-up, block the fluid passage, make and form a closed chamber between piston 3 and cylinder liner 2.Along with increasing of tolerance, piston 3 is pushed up, until be locked on fishing neck 1 by spring pin fixed 9.In this process, piston 3 drive connecting rods 8 and lower spider 6 up, make spring 7 be in compressive state, packing element 5 is in swelling state, and then a packing face occurs in pit shaft, and the gas of plunger below can't be passed through.Gas is assembled below plunger, and it is up that energy is increased to the liquid that to a certain degree just promotes plunger and its top, and when plunger arrived well head, the liquids and gases on its top were plucked out of.
2, plunger is descending
When the liquids and gases of plunger upper part are plucked out of, the gas of plunger bottom is released, and at this moment plunger is in the relatively low pressure district, and plunger is Automatic-descending under action of gravitation, hollow steel ball 11 falls, open the fluid passage, and the closed chamber pressurized gas discharge, and spring 7 discharges elasticity, make fixed 9 releases of spring pin, piston 3 is descending, and packing element 5 shrinks playback, until piston 3 is locked on middle spider 4 by spring pin fixed 13.When plunger arrives the down-hole and is located the device top, the circulation of beginning next cycle.
